Performance testing is an essential aspect of software development, ensuring that applications can handle the demands of real-world scenarios. Traditionally, performance testing has been conducted in isolated environments, detached from the production environment, leading to potential discrepancies between test results and actual performance. However, with the evolution of technology and methodologies, the paradigm of performance testing has shifted towards conducting tests directly in production environments. This paradigm shift, combined with the practice of continuous profiling, has revolutionized the way organizations approach performance optimization and stability.

In this conference talk, he will delve into the fascinating world of performance testing in production and low-overhead continuous contextual profiling, exploring the benefits, challenges, and best practices associated with this innovative approach.
